实现思路
有帮助的话各位哥哥可以点个关注收藏哦
后端生成六位随机验证码，存入redis（key：邮箱号，value：验证码），校验的接口/code/login通过redis 查询code是否存在，如果满足条件，可以自己加一些登录注册的业务之后在返回需要的值。
有帮助的话各位哥哥可以点个关注收藏哦
一、后端部分（文件目录可以看图2）
1.redis部分
代码如下（示例）：
const redis = require('redis');
const client = redis.createClient(); //默认没有密码 127.0.0.1 端口也是默认
// 如果是连接远程的话
// redis[s]://[[username][:password]@][host][:port][/db-number]:
// const client = createClient({
// url: 'redis://alice:[email protected]:6380'
// });
client.on('error', (err) =>
console.log('Redis Client Error', err
));
client.on('connect', () => {
console.log('redis connect success');
})
client.connect();
module.exports = client;
2.nodemailer部分
代码如下（示例）：
//nodemailer.js
const nodemailer = require('nodemailer');
const { mailConfig } = require('../config/index')
const { user, pass } = mailConfig
let transporter = nodemailer.createTransport({
//node_modules/nodemailer/lib/well-known/services.json 查看相关的配置，如果使用qq邮箱，就查看qq邮箱的相关配置
service: 'qq', //类型qq邮箱
port: 465,
secure: true, // true for 465, false for other ports
auth: {
user,
pass
}
});
//pass 不是邮箱账户的密码而是stmp的授权码（必须是相应邮箱的stmp授权码）
//邮箱---设置--账户--POP3/SMTP服务---开启---获取stmp授权码
module.exports = function (email, code) {
// const {username,password,email} = user
let mailOptions = {
from: '' , // 发送方
to: email, //接收者邮箱，多个邮箱用逗号间隔
subject: `欢迎登录,你的验证码${code}`, // 标题
html: `<head><base target="_blank" /><style type="text/css">::-webkit-scrollbar{ display: none; }</style><style id="cloudAttachStyle" type="text/css">#divNeteaseBigAttach, #divNeteaseBigAttach_bak{display:none;}</style><style id="blockquoteStyle" type="text/css">blockquote{display:none;}</style><style type="text/css"> body{font-size:14px;font-family:arial,verdana,sans-serif;line-height:1.666;padding:0;margin:0;overflow:auto;white-space:normal;word-wrap:break-word;min-height:100px} td, input, button, select, body{font-family:Helvetica, \'Microsoft Yahei\', verdana} pre {white-space:pre-wrap;white-space:-moz-pre-wrap;white-space:-pre-wrap;white-space:-o-pre-wrap;word-wrap:break-word;width:95%} th,td{font-family:arial,verdana,sans-serif;line-height:1.666} img{ border:0} header,footer,section,aside,article,nav,hgroup,figure,figcaption{display:block} blockquote{margin-right:0px}</style></head><body tabindex="0" role="listitem"><table width="700" border="0" align="center" cellspacing="0" style="width:700px;"><tbody><tr><td><div style="width:700px;margin:0 auto;border-bottom:1px solid #ccc;margin-bottom:30px;"><table border="0" cellpadding="0" cellspacing="0" width="700" height="39" style="font:12px Tahoma, Arial, 宋体;"><tbody><tr><td width="210"></td></tr></tbody></table></div><div style="width:680px;padding:0 10px;margin:0 auto;"><div style="line-height:1.5;font-size:14px;margin-bottom:25px;color:#4d4d4d;"><strong style="display:block;margin-bottom:15px;">尊敬的用户：<span style="color:#f60;font-size: 16px;"></span>您好！</strong><strong style="display:block;margin-bottom:15px;">您正在进行<span style="color: red">用户登录</span>操作，请在验证码输入框中输入：<span style="color:#f60;font-size: 24px">${code}</span>，以完成操作。</strong></div> <div style="margin-bottom:30px;"><small style="display:block;margin-bottom:20px;font-size:12px;"><p style="color:#747474;"> 注意：此操作可能会修改您的密码、登录邮箱或绑定手机。如非本人操作，请及时登录并修改密码以保证帐户安全<br>（工作人员不会向你索取此验证码，请勿泄漏！)</p></small></div></div><div style="width:700px;margin:0 auto;"><div style="padding:10px 10px 0;border-top:1px solid #ccc;color:#747474;margin-bottom:20px;line-height:1.3em;font-size:12px;"><p>此为系统邮件，请勿回复<br>请保管好您的邮箱，避免账号被他人盗用</p><p>网络科技团队</p></div></div></td></tr></tbody></table></body>`
};
transporter.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('mail sent:', info.response);
});
};
3.发送邮件的接口
router中引入redis 和 nodemailer 部分
const client = require('../utils/redis');//redis使用
const nodemailer = require('../utils/nodemailer');//发送邮件
//成功返回参数
function success (res, total = null) {
if (total) {
return {
code: 200,
data: res,
msg: '成功',
total
}
} else {
return {
code: 200,
data: res,
msg: '成功'
}
}
}
//失败参数
function fail (msg) {
return {
code: 500,
msg
}
}
// 生成六位随机验证码
function createCode () {
return parseInt(Math.random() * 1000000)
// return 'xxxxxx'.replace(/[xy]/g, function (c) {
// var r = (Math.random() * 16) | 0
// var v = c == 'x' ? r : (r & 0x3) | 0x8
// return v.toString(16)
// })
}
//发送验证码邮件
router.post('/send/email', function (req, response, next) {
let code = createCode() //随机生成验证码
const mail = req.body.mail//请求携带的邮件
client.set(mail, code).then(res => { //存入redis
//设置成功发送邮件
nodemailer(mail, code)
response.send(success())
})
client.expire(mail, 60);//设置过期时间 60s 前端六十秒可以重新获取
});
4.后端校验验证码是否有效
//通过验证码登录
router.post('/code/login', function (req, response, next) {
/* 这里 用户名就是 邮件 密码就是code */
const { mail, code} = req.body
client.get(mail).then(res => { //从redis查询数据
if (code== res) {
console.log('验证成功')
//do something
// ...
response.send(success({
user: mail,
}))
} else {
console.log('验证失败')
response.send(fail('验证失败'))
}
})
});
二、前端部分（使用的element-admin）
1.正则验证输入的是否是邮箱号
const validateUsername = (rule, value, callback) => {
let reg = /^[A-Za-z\d]+([-_.][A-Za-z\d]+)*@([A-Za-z\d]+[-.])+[A-Za-z\d]{2,5}$/;
// !reg.test(value)
if (!reg.test(value)) {
callback(new Error('请输入正确邮箱号码'))
} else {
callback()
}
}
2.前端login页面完整代码可以参考（有部分字段需要修改），这个包括60秒倒计时的效果。
